### Detecting Collisions

The Collision Detection option is not available for Portable devices.

The Operation | Graphic Display Window | Collision Detection menu option (CD) displays the Collision Detection dialog box. The CD module detects collisions between the probe and CAD surfaces. It ignores all CAD curves, lines, and points. As a result, only CAD files that fully describe the part using surfaces are suitable for collision detection. (The CD algorithm doesn't use the actual surface definitions, but rather the surface tessellations [or graphical approximations], which are also used to render solid views using the OpenGL graphics language.)

Changing Animation Speeds: If you want to modify your offline animation speeds, see the Execution area on the General tab in the Setup Options dialog box (Edit | Preferences | Setup). In addition, see the "Executing and Debugging Measurement Routines Offline" topic in the "Working in Offline Mode" chapter.

Viewing Collisions for a Range of Selected Items

You can also limit the collision detection items by selecting a range of one or more features in the Edit window, and perform the collision detection on only those selected features.

To do this:

1. In the Edit window, select the range of features. Either click and drag the selection (if in Command mode), or click on the first feature, press the Shift key on your keyboard, and then click the second feature to establish the range of features. (If in Summary mode, you can also press the Ctrl key instead of the Shift key on your keyboard.)

2. Right-click in the Edit window. A shortcut menu appears.

3. Choose Selected Items Collision Detection. PC-DMIS automatically performs the collision detection on those features and draws path lines as PC-DMIS processes the features. A check box then appears next to the shortcut menu item.

If you want to immediately select a different range of features, you need to right-click in the Edit window, clear the Selected Items Collision Detection first, and then re-select it for the new selection.
